<---  Back to Calculators

Our Top Soil Calculator is here to help you try to work out how much top soil and how many bulk bags of soil you require to cover your area. 

Soil, as with aggregates, is subject to a phenomonon called "bulking factor" and each media has its own bulking factor to use. So whether it is ballast, sharp sand, shingle or decorative aggreagtes, we have tried to offer an estimate towards these figures below. Please note there are many factors we cannot control so use this as a rough guide rather than a full and final figure. 



Soil Bulking Factor

The bulking factor is a measure of how much the volume of the sand increases due to the spaces between the particles. In other words, it's a way to correct for the fact that the sand doesn't take up as much space as you might think. As an example: Let's say you have a bucket that can hold 10 liters of sand, and you fill it up with sand. But when you pour the sand out, you only get 8 liters of sand, because of the spaces between the particles. This means that the bulking factor for your sand is 1.25, because 10 / 8 = 1.25.

In short, the bulking factor is a way to make sure you have enough sand to cover the area you need, even if it doesn't look like you have enough at first glance. It's a handy tool to have in your toolbox when working with granular materials!
